PT6 Fuel Pumps
Herber Aircraft is now a global distributor of Eaton fuel pumps. The Eaton fuel pump is compatible with all variants of the popular PT6A engine.
The PT6a pump inlet feeds into a 74 micron nominal inlet screen which then flows directly into the gear stage inlet. The gear stage sends pressurized fuel through the 10 micron nominal discharge filter and on to the engine fuel control.
There is no performance difference between the different pump models. The only differences are in port connection schemes, pressure ports, drive shaft length, and one model contains a pressure regulating valve.
